naturally aspirated, non stroker, 60 over, 360, 500hp, is it possible?

* WOW really? Tell us what was done to the 340.My stroked 318/390 made less than that..

you need to find the right dyno.......dyno hp are correct for standard air 60 degrees....29.92 baro...water temp controlled...

dyno is a tool ...to make adjustment ...breaking in engine...compare carbs...intake manifold...compare the changes....to accept the HP without running the car down the track is foolish...
